PATENT oFF DIAGRAM CHART.

- Application led March 24 1922'. Serial No. 548,27/0.

To all 'whom it may concern.'

Be it known that I, Mano -LOEWENTHAL, a citizen of the United States, and a resi'- dent ofthe city, county, and State of New -York, have invented certain new and useful Improvements in a vDiagram Chart, of

which the following is a full, clear, and

exact description.

This invention relates to measuring and drawing devices and in particular to one which may be used by real estate, insurance, and other persons interested in the charting of property.

A particular ob]ect of the invention is the provision of a device through the use of which the position of real estate property may be diagrammatically set down on paper to scale and in correct proportions.

v further object of the invention is to provide in con]unction therewith suitable markings through the medium of which,the

sizes of lots may be laid ol' and means for' drawing without a ruler or square, parallel lines necessary in charting real estate locations.

' Drawings.

Figure. 1 is a plan view of my diagram chart or stencil, showing the slots and open- 'ings therein, together with the necessary etched lines which divide oli the chart to scale.

Figure 2 is a' section of the chart taken on the line 2-'2 of Figure 1, and showing the relative thickness thereof.

Figure 3 is a digram drawn with the aid of my chart showing the location of a piece of property, the same being laid out to scale, and therefor showing the relative size of a ece of property.

igure 4 is another diagram, in which an avenue passes diagonally, the location of property at the'intersection of street and alvenue being to scale with the use o the c art.

Description.

versely extending(` parallel slots 10, all orn l which terminate adjacent each yother to leave a space 11 therebetween fonthe obvious purpose of preventin the parts surrounded thereby from/falhng out or otherwise weakeningfthe stencil.

I'n laying out the slots, four streets have been formed which surround a .center block 12 which' is divided into hundred foot parts 13 by lines 14' etched Von the stencil.

Across the stencil and passing through the center block'12 are formed the diagonally disposed parallel slots 15 whicht are n usedto. draw a diagonally running street 'or avenue. At the intersections of the etched lines ,there 'are provided small holes 17 through Mwhich a pencil point may be inserted to mark` the paper upon which ythe chart is being drawn, and each one hundred feet of etched line is marked 100 to denoteA block 12 the etched lines 16 terminating in the holes marked 25, 50 and 7 5- serve to show how the lots, at the intersection of the diagonall extending avenue, and street, would be lai out.

In the upper let-handcorner of block 12 there are laid oli etched lines 18 dividing the lot' into four twenty-tive foot lots, the lines terminating in the holes which are marked s uccessively 25, 50, 75, the middle line being extended to allow for laying off an angular twenty-'five foot lot which would face on two streets one at right angles to the other. v

The etchings 19 and holes in the lower left-hand corner of the block are provided for laying oii' a series of lots having the same depth and are marked successively $25, 50,' 7,5, 100, with the width of each individual lot being noted as 25.

In the lower right-hand corner, the lines 20 are of different lengths, each increasing progressively by twelve and one-half feet, and terminate in the holes `which are correspondingly designated to indicate the length in feet, starting at 5121A of their respective lines. It will be-noted that the lines 20 are spaced twelve and one-half feet apart, so that any width of lotmay be laid oi.

The chart is further provided with a suitable scale 21 showing the relative sizes of the markings thereon, and the scale to which the chart is laid out, it being understood that if any other scales were necessary, additional charts or stencils could be made to suit.

VViththe aid of my chart it is then only necessary todraw the streets as shown in Figure 3, through the slots 9 and 10, and

connect 'the lines drawn therethrough, thenl the chart is used to llay off the lots 22 illustrated, their location, depth and Width being readily obtainedy from the chart by usin'" any of the etched lines and the assoclated lholes which are kproperly marked to show` both depth and width.

lVhen, as seen in Figure 4, a diagonally disposed avenue is needed, the same is drawn through the slots 15 of the chart, and in laying o a lot 23 which is bounded on one Side by the avenue, the etched lines-'16 and associated holes are used;

When using the chart to obtain the various measurements and point locations, it is easy, because of the transparency of the chart, to locate the scale or indices as desired i on the diagram. For instance, if a diagram was being used to show the location of a lot 50 feet from one street and facing on` an'- other, the lines 18 and 19 would be employed to locate the side of the lot nearest the street from which the measurement is taken. Then the chart would be shifted so as to employ' the calibrations and lines 2O vWhere it would be found that measurements on the divisions of 121/2 feet are employed, and by use of which, it would be easy to showl a line drawn with reference to the first inscribed line, a distance 371/2 feet. The transparent feature of the chart admits of its use in many Ways,

for adding to` or 'correcting diagrams which have been previously produced.
